Currently working on multiple apps hitting anywhere between 5k and 150k maps loads a day, costs are zero because we do not do things outside of the free usage tier. The Maps Embed API (the one you see on websites) is pretty clear on that: https://developers.google.com/maps/documentation/embed/usage...

    Pricing for the Maps Embed API
    All Maps Embed API requests are available at no charge with unlimited usage.

    Other usage limits
    There are no short-term (queries per second) or long-term (queries per day) limits on the Maps Embed API.

Similar things apply to the Maps SDK for Android. Seeing the watermark means that there's either no API key being sent with the request or, in relatively new developments, that you haven't enabled billing/inputted a credit card. Which is a scary thing to do when you know that you're not doing anything out of the usage limits... but what if Google suddenly decided that ?
